Z2 Plus Boot issues - Lenovo ZUK Z2 (Plus) Questions & Answers

I was on AEX and tried a new roms (Pixys, Evolution, Pixel Experience etc) and none of them booted the android.
Tried to restore AEX and even that is not booting. Phone keeps rebooting in loop without booting to any os including the restored backup.
Evolution and pixel after a clean installation says "no os".
Phone stays in start mode and does not move beyond this point.
Phone boots to twrp recovery.
Any idea what is wrong? Have corrupted the phone that it can't be used?
Is there a way out?
Quick solution would be highly appreciated.
Thanks

Anyone has a solution/suggestion for this?Deperate now since there is no alternate phone.
Thanks again

The phone boots recovery and adb commands work whereas fastboot commands don't work. I am able to flash vendor2factory and rom successfully with no error but the phone still not boot android but vibrates and goes back start screen and if i don't press any keys it restarts again after showing the ZUK logo.
I hope i have been able to explain the situation. I am still not able to boot the android despite trying more than one rom.
Anyone has any clues? Thanks

I am having the same problem. I was in pixel experience and i flashed latest pixel experiences august security patch, it showed no os but it booted. But there were several bugs in the rom, i thought it was roms problem and then i tried to flash evolution, it again showed no os after flashing and then i got stuck at evolution x boot logo. So, i tried to qfil zui but to no avail, the flashing process won't even start the qpst tool just freezes after pressing the download button. Then in the twrp i noticed that battery percentage is different at different times sometimes it shows correct value but somes it won't so i thought that the problem might be from twrp and then i flashed new twrp but again same problem. Then i flashed arrow os 10.0 without gapps, it booted successfully then i flashed gapps. After sometime i tried to flash evolution x but got stuck at boot logo again. Finally i flashed arrows os again it booted successfully (i flashed rom and gapps separetly)
So, FINALLY THE TEMPORARY SOLUTION IS TO FLASH ARROW OS IT WILL BOOT SUCCESSFULLY BUT THEN AGAIN OTHER ROMS WON'T BOOT. IF I FIND ANY SOLUTION I WILL POST HERE

When you qfil, the recovery will be lost i think. But since you cannot enable usb debugging i think you wont be able to flash twrp.

I think the problem is our phone is not able to boot big rom i.e. roms of size close to 1gb or more than 1gb since arrow os without gapps is only 600mb my phone is able to boot. If you are able to find the solution or get your phone repaired at any cell repair centre please let me know

bro is your phone working now

I think I hardbricked my Zuk z2?

So guys
I was on twrp and tried to flash a new rom but when it rebooted after the install, my Zuk z2 died.
It does nothing now. If I press the powerbutton for a long time it shortly vibrates for one second and the notification light also lights up for 1 second, but does not boot up. I tried volume combinations, don't work either.
What can I do guys?
Well, this guy managed to fix it
. Not sure if its the best way to fix it but it's still something

Use this if you didnt success from other methods.

My video. The brick occurs when you usually backup a room with one version of twrp, flash another variant of twrp and then restore the nandroid from before.
Happened to me. Flashed MIUI, and then tried to restore a nandroid (not realising the TWRP changed).
Hope the video helps. Plus then you have a cable premade in case it happens again

Hello. Maybe you can give me some advice. I am stuck in engineering/diagnostics mode after I accidentally selected that option when I was in the bootloader trying to flash TWRP.
Basically, I had installed TWRP and Mokee 7.1.1. I wanted to check out the original chinese ROM so I relocked, flashed with QFIL, etc. I had first flashed MM, then I flashed latest chinese Nougat official.
I didn't like it, so I was trying to unlock the bootloader again, and in the process I ended up selecting the diagnostics/engineering mode. The phone was stuck there and I had no way of accessing the bootloader to reflash with QFIL or MiFlash
TO try to fix, I used the deep flash method you describe in the video, only I found it in zukfans. I was able to open the 9008 port, flash with QFIL/MiFlash. Even though both tools describe the flash as successful, on boot, it goes back to engineering mode.
How to I get out of there? Is my phone done?
Thanks!

Moto G5 not booting after changing boot animation

I recently tried to change my boot animation with the "Boot Animations for Superuser" app on the Play Store and now my phone won't boot anymore, I had the latest PixelExperience 9.0 installed and was rooted with magisk 20. When I boot up the phone it displays the "Your phone has been unlocked and can't be trusted message for around 60 seconds whilst vibrating once or twice and after that, the screen turns black and it continues to vibrate every couple of minutes. I still have access to TWRP and fastboot but I haven't found a way to get my boot animation back yet. I have flashed numerous boot animations but to no avail. I don't want to revert back to stock because I have seen various posts around here about people losing their IMEI numbers.
Does anybody have a solution?

Dirty Flash the PE rom and it will bring back the PE boot animation for your device and boot your device.

Try formatting system from advanced wipe
Then flash rom zip gapps and magisk
If it doesn't boot then your data partition has also been modified and unless you know what changes were made or you created a twrp backup before the changes were made then you will also have to format data too

Flash the magisk uninstall zip first to clean up any modules you may have
Also if you are flashing cannery builds of magisk try going back to stable versions

Clinically dead Redmi 5A - please help

Hi to all, I just want to ask for some advice or tips. The thing is:
I have one old Redmi 5A Riva. It was lying in the drawer some time, so I decided to try to unlock the bootloader and flash some custom ROM.
So, I unlocked the bootloader - OK
Then I flashed TWRP - OK
Then I decided to make root on stock firmware - OK
Then I tried to flash Lineage OS 17 - after flash it stopped booting.
So I tried to flash Lineage OS 18 - it started booting again but I found out that phone doesn´t detect an USB cable, so I wanted to flash some other ROM instead.
But after few moments TWRP suddenly disappeared (volume up + power on stopped working, only vol. down and power on worked to fastboot) - kinda weird, I said to myself Now I am f**ked up because Lineage 18 was not rooted, I wanted to do it later, so I couldn´t use TWRP app to reflash it.
But after few moments there appeared stock recovery menu, so I thought okay, maybe its not dead, so I try to flash just stock rom. I tried MIUI 10, but again - not booting.
So I did wipe again and tried MIUI 9 - flashing via fastboot and used flash_all.bat attached to rom - it booted up and worked, so I enabled USB debugging again and tried OMNI ROM. I flashed it, after flash it boots up, but after few second screen goes black and nothing else happens.
I am kinda annoyed with this , I flashed many phones, but only Xiaomi makes these weird problems.
Can someone help me to fix this?

Stuck on boot logo after flashing (the wrong thing...)

Hello!
Today I started to install TWRP and flash RR. After a few problems with Odin, I successfully installed TWRP 3.2.3 on my phone.
I have tried many times to install RR because each tutorial said different ways and I still do not have much knowledge about that.
3 hours ago I tried to install RR for the x time and tried to install from zip folder RR the boot.img file. But I did not select it as boot but as recovery.... After that I rebooted. And since then the phone gets stuck at the boot logo.
I cant't enter the download or recover mode. Can only restart it by holding down all buttons or the power and volume down.
I know that it was not the best idea. My phone is also 3 years old now. And that's why I'm thinking about buying a new one.
My new one would otherwise be the Samsung Galaxy A21s.
